Hi
There will be plenty slow running 2 cyl diesel engines that will make
the same, still the Sabb 22 Hp. will proberly outlive most , --- with
these engines what you gain is not any high efficiency but a stable
realible workhorse, also the noise are not bad. Still there be plenty
simular types , 1800 rev. will make it work for decades that's the
quality if these engines, _not_ the pover output.
